Another update to not install.

Odd. North American PSPs already have UMD music functionality, do they not? On the sampler disc that came with the PSP, it had a UMD icon under each of Music, Video and Game...

All these updates are obviously targeted to the v1.0 psp sony could care less about the rest as long as no one figures out how to get homebrew to execute succesfully on 1.5+ sony does not want you to have any psp's running the original firmware

I believe the same was for JP PSP's as well.

EDIT: The update allows you to play music in the XMB, similar to playing music from the MS duo.


On a side note, anyone else notice that 1.52 is SMALLER than 1.51?? They must have really made there code more concise.

[engstrom]

Now if I was at Sony I'd put a web browser in the next firmware update to really annoy people ;-)

[RATiX]

It wouldn't annoy many. Those that have 1.5+ anyway would install it, and those with 1.00 would make a homebrew browser eventually. Sony just needs to allow homebrew.

Whoops...my bad :\

Maybe they included more in the original patch than was really needed, a rush job, and they cleaned up in the meantime.

Another hypothesis: one reason the 1.52 update is smaller than the 1.51 is because there is no screen telling you what you're getting. All it says is 1.52 Update and then Start.

I haven't installed it on my PSP, so perhaps there is the "this is what's inside" screen later on, but if they ripped that whole section out, that removes the notifications of
*UMD music playback from XMB
*More security strengthening
*Security enhancement (only would be displayed if you have 1.50, not 1.51, seeing as this is in 1.51 and presumably in 1.52 as well)
*More Languages (Displayed on 1.00 PSP only, same reason as above)
*Everything else that was in 1.50 but not 1.00 (Displayed on 1.00 only... duh)

If you get what I mean, that cuts out a whole screen, and a bunch of strings. That might help explain for some of the size loss.

[zigzag]

No, that screen is there after you select "Start" and you can still cancel it after that point -- also, that would hardly affect size.

[Drakonite]

Er... speculating about the reasons a filesize is different is pointless, and I'd dare go as far to say stupid unless there is a significant (10-20% or more) difference.

There is a tremendous number of things that can impact filesize, and the majority of them are inconsequential to anyone other than the people wanting to make the filesize smaller. Bitdepth of an image, optimization level of a binary, order and how tightly files are packed together in a filesystem, or any of hundreds of other things. Hell, once the idea of compression being used at some point anywhere is put in the mix extremely trivial changes to the data or even reordering data can cause a noticable impact, not to mention changing the exact compression method or ratio.
